With InnovairFlex™ duct smoke detectors, one unit can accommodate multiple installation footprints to overcome mounting constraints — a first for duct smoke detectors. The InnovairFlex product line also offers superb false alarm immunity, a broad temperature range from -4°F to 158°F (-20°C to 70°C), easily visible status indicators and a readily accessible test feature. For increased ease of installation, technicians can now install the new sampling tubes for InnovairFlex from the front or back without using tools by snapping them into place. In addition, for retrofit applications, designers have ensured that sampling tube spacing lines up with existing models. Finally, the range of InnovairFlex products and accessories can meet any code requirements and are backward compatible to existing Innovair products.
